This plugin provides the <code>[iagc]</code> shortcode, which can be inserted on a WordPress Page or Post to display the official Copyright notice, a C with a circle around it (“©”) required legally in many countries to protect (“copyright”) many forms of intellectual property.
The <code>[iagy]</code> shortcode displays the current year. To display the Copyright symbol followed by the current year, use the <code>[iagcy]</code> shortcode.
Although not required in a Copyright notice, the <code>[iagm]</code> shortcode displays the name of the current month and the <code>[iagd]</code> shortcode displays the current day of the month.
Note that the day, month and year are truly Current, accurate to the moment the Page or Post is displayed, based on the Timezone set in WordPress General Settings.
To provide compatibility with previous Versions of this plugin, the <code>[c]</code>, <code>[y]</code>, <code>[cy]</code>, <code>[m]</code> and <code>[d]</code> shortcodes will still work, but one or more of them will be disabled if any other activated plugin or theme defines the same shortcode, so as not to interfere with that other plugin or theme.
